WILLIAM L. PURPLE, OF ALBANY, NEW YORK.

VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 343,153, dated June 1,1886.

Application filed February 9, 1886. Serial No. 191,387.

(No model.)

To all whom it may concern:

, Be it known that I, WILLIAM L. PURPLE, of the city and county ofAlbany, in the State of New York, have invented new and useful afi'ordmeans for permitting the running-gear.

to receive a lateral jar when passing over ruts, rough pavements, &e.,without imparting a lateral motion to the body of the ve hicle. Thisobject I attain by means of the construction illustrated in theaccompanying drawings, which, being herein referred to, form part ofthis specification, and in which Figure 1 is a perspective view of thebody and springs of a road-cart provided with my improvement; Fig. 2, arear elevation of the same; Fig. 3, a .detached and enlarged perspectiveview of one of my hangers and swing ing shackles for connecting the bodywith the springs; Fig. 4, a perspective view of part of a buggy, showinga modification of my invention as applied to elliptic springs; and Fig.5, an enlarged perspective view of the swinging shackle shown in Fig. 4.

As represented in the drawings, A is the body of the vehicle, which maybe of any re quired size and shape.

The springs shown in Figs. 1 and 2 consist of two transverse springs, B,and two side springs, B, the latter being secured to the axle G, and thefour beingjointed together by shackles I) to form what is known to thetrade as a platlorm-spring. The upper leaf of each transverse spring Bhas its opposite ends coiled to form eyes I) for receivingshacklepins.as hereinafter set forth. Hangers D are secured at oppositesides to the underside of the body A, so that the transverse springs Bwill pass freely through them. Each ofsaid hangers is provided with aswinging shackle, E, that is made in the form of an open loop, and ispivoted to the hanger by a transverse pin, 6, in such manner that saidshackle will swing freely in the hanger. The upper end of the shackles Eis pivoted to its appropriate eye b by means of the shackle-pin e. \Vhenthe bodyAis attached to the springs B in the manner above described, andcontains any weight, the running-gear may receive anylateral joltwithout imparting a sudden or jolting motion to the body, and by thismeans when a top is used upon the vehicle the usual and annoyingswitching of the top is avoided.

In the modification shown in Fig. 4 the strap F is secured on the underside of each end of the body A of a buggy or other vehicle. Said strapis provided with an eye, f, for re ceiving the lower pivot-pin, e, of aswinging shackle.

The shackle E is made with a single vertical bar havinga lowerhook-shaped off-set, e, which is pivoted to one of the eyesf, and anupper hookshaped offset, 0 which is pivoted by the pivot-pin g to one ofthe eyes 9, which are formed at each end of a strap, G, that is fixed toa bearing-bar, H, which is secured to the upper side of each transveisespring B, as shown in Fig. 4. WVhen preferred, the bearing-bar H may bedispensed with; 111 such cases the upper leaf of the springs will beprovided with eyes, as hereinbefore described, and the upper end of theswinging shackles will then be connected directly to said springs.

The pendulous motion of the swinging shackle shown in the'modificationwill permit the running-gear of the vehicle to receive a lateral joltwithout imparting a like motion to the body of the vehicle.

I claim as myinvention- 1. The combination, with the vehicle-body A,provided with hangers D, having swinging shackles E pivoted thereto, ofthe transverse springs B, pivotally connected to said swinging shackles,all being constructed and arranged'to operate as herein specified.

2. The combination of the body ofa vehicle having swinging shacklespivoted thereto and transverse springs provided with eyes to which thesaid swinging shackles are pivoted, substantiall y as and for thepurpose specified.

\VILLIAM L. PURPLE.
